Demario Richard and Kalen Ballage combined for 168 yards rushing and Arizona State forced four turnovers to lead the Sun Devils to a 30-10 win over Utah on Saturday.
Manny Wilkins threw for 140 yards on 19-of-29 passing to help Arizona State (4-3, 3-1 Pac-12) snap a seven-game road losing streak.
Tyler Huntley started for Utah at quarterback after sitting out losses to USC and Stanford with a shoulder injury. Huntley struggled in his return, throwing for 155 yards and four interceptions on 19-of-35 passing.
Arizona State's defensive domination of Washington turned out to be no fluke. The Sun Devils shut Utah down cold before halftime. They allowed the Utes to gain just 93 total yards and seven first downs in the first half.
Two of Utah's first half drives ended with interceptions from Huntley.
Arizona State mounted several long drives to take a 16-0 halftime lead. Brandon Ruiz made field goals from 47, 40 and 30 yards in the first quarter. The Sun Devils broke through with their first touchdown on a 1-yard run from Demario Richard with 40 seconds remaining in the half.
Matt Gay made a 53 yard field goal to cap off Utah's opening drive of the third quarter. Arizona State answered when Wilkins stretched over the goal line on a 1-yard keeper, extending its lead to 23-3 with 4:45 left in the third quarter.
The Utes kept the drive alive with a pair of targeting penalties that led to ejections for Donovan Thompson and Corrion Ballard. Ballard's penalty gave Arizona State first-and-goal at the Utah 1 after the Sun Devils were facing fourth down.
Jay Jay Wilson put the final nail in the coffin for Utah when he returned an interception 20 yards for a score midway through the fourth quarter. Huntley's fourth interception of the game gave the Sun Devils a 30-3 lead.
Utah's lone touchdown came on a 2-yard run from Devontae Henry-Cole with 2:41 remaining.

Zach Green scored the Wildcats touchdown in the first overtime and had a three-yard run to open the second extra period before Tate scrambled in the backfield to avoid a sack and found Wolma open near the goal line for the game-winner.
California answered with Vic Enwere's 1-yard touchdown run but came up short on a two-point conversion attempt when Arizona linebacker Colin Schooler deflected a Ross Bowers pass intended for Jordan Duncan near the back of the end zone.
Bowers completed 29 of 49 throws for 301 yards and two touchdowns, one in the first overtime, but was intercepted twice. The Wildcats (5-2, 3-1 Pac-12) wasted leads of 21-7 and 28-14 before holding off the Bears (4-4, 1-4).
